In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Integra are reminded to check the back seat if they opened the rear door before starting out. The A4 doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Integra offers an optional Low-Speed Braking Control that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The A4 doesn’t offer backup collision prevention brakes.
The Integra has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the A4’s blind spot costs extra.
To help make backing out of a parking space safer, the Integra has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the A4.
The Integra’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The A4 doesn’t offer a driver alert monitor.
Both the Integra and the A4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available rear parking sensors.
